Two poles of heights 23m and 30m stand on the plane ground. If the distance between their feet is 24m, find the distance between their tops.

Two poles of heights 6m and 11 m stand on a plane ground. IF the distance between the feet of the poles is 12m, find the distance between their tops.

Find the distance between (5,6)(-2,3).

Find the distance between (-2,3) and (5,-3).

P is a point on the segment joining the feet to vertical poles of heights a and b, The angles of elevation of the tops of the poles from P are 45^@ each. Then the square of the distance between the tops of the poles is:

A tree breaks due to storm and the broken part bends so that the top of the tree touches the ground by making 30^(@) angle with the ground. The distance between the foot of the tree and the top of the tree on the ground is 6m. Find the height of the tree before falling down.
